Camera app stays black/doesn't react after update to Android 9
What happened?
I updated my Fairphone 2 on Android 9. Afterwards, the camera screen stayed black when I wanted to take a picture. I already cleared the data stored in the camera app and the cache and restarted the phone. This brought no change.
Workaround/solution
Wiping cache and data of the Media storage process/app. You can find it by going to Settings > Apps > See all apps > Three dots > Show system > Media storage.
Once there, first try:
App-Info -> Storage -> Clear cache
If this does not work, try:
App Info -> Storage -> Clear storage
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
